This backwards-running clock shows your pupils how much time they have left to hand in or finish their work, to the minute.The special thing about this clock is that the clock face is mirrored. The coloured disc - and therefore the time - count down clockwise as usual when learning the time. The visual, analogue representation of the remaining time in the coloured field gives time information at a glance without affecting concentration on the actual task.In addition, the visualised time representation helps the pupils to allocate their time independently. Due to the battery operation, the clock runs silently. At the end of the set running time, a signal sounds that can be made loud/quiet or silent. A special feature of this clock is that 8 different levels can be selected for the duration of the sequence signal. With base, wall suspension hole and rear magnet for attaching to the board. Size: approx. 20 x 20 cmBattery type: AA (x2) The accurate remaining time display encourages understanding and responsibility with regard to: Time Use of time Time management
